sixtracklib/cuda: try to add explict Cuda libraries to link libraries dependencies

- Due to the native Cuda support in Cmake >= 3.8, no explicit search for the
 cuda libraries is performed and needed. Still, it seems that there is a problem on
some systems and in combination with nvrtc

This change attempts to formalize the search for these shared objects
within the framework of of native Cuda support in Cmake
